Since I have no experience with these holsters, someone could correct me if I'm wrong. Once you press the button to release the gun from the holster, you finger rides up the side of the holster as you pull the gun out of it. Therefore, you should no longer have any pressure pushing down with your trigger finger by the time the gun is released. I see your concern, but you might be a little over-cautious. Like I said though, I could be wrong. Also, I personally believe leather would be a better option. Once again, I could be wrong, but I would personally prefer leather touching a high-end gun than hard plastic any day. You may get more "wear marks" from leather from sliding in and out, but I would guess that you're also more likely to get deeper scratches from plastic.
